Strawberry fruit develops dark-brown lesions that spread, becoming tough and leathery with unpleasant odor. Phytophthora cactorum transmits via rain splash from mummified fruit and soil. Improve drainage with 8-10 inch raised beds, avoid standing water, and mulch to prevent soil splash onto fruit.
Improve drainage of soil before planting so there is no standing water. Plant on beds raised 8 to 10 inches to improve drainage, or use drain furrows.
